With Ripples, you can now see how your public content was reshared over time on Google+, and what users were saying about it. To try it out, just find a public post and select ‘View Ripples’ from the drop-down menu in the upper right-hand corner of the post. You’ll see a number of circles that each correspond to a user that has reshared your content, and inside the circle you’ll see the people who have reshared the link from that person (and so on). Circles are roughly sized based on the relative influence of that person -- so the larger a person’s circle is, the more reshares have resulted from their original reshare.
